Raspberry plant named ‘DrisRaspTwo’

ABSTRACT

This invention relates to a new and distinct variety of raspberry plant named ‘DrisRaspTwo’ which is primarily characterized by medium-sized, medium-red fruit that mature to a dark red color and having an early bud burst, is disclosed.

Genus and species: Rubus idaeus L.

Variety denomination: ‘DrisRaspTwo’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct raspberry cultivar designated ‘DrisRaspTwo’ and botanically known as Rubus ideaus L. This new raspberry variety was discovered in Santa Cruz, Calif. in May 2004 and originated from a cross between the female parent raspberry plant ‘Driscoll Cardinal’ (U.S. Plant Pat. No. 14,903) and the proprietary male parent raspberry plant ‘W776.1’ (unpatented). The original seedling of the new cultivar was asexually propagated by stolons or tissue culture, at a nursery in Santa Cruz, Calif. ‘DrisRaspTwo’ was subsequently asexually propagated and underwent further testing at a nursery in Santa Cruz, Calif. for five years. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Santa Cruz, Calif.

-   -   1. Medium-sized, medium-red fruit that mature to a dark red         color; and     -   2. Having an early bud burst.

DESCRIPTION OF THE PHOTOGRAPHS

This new raspberry plant is illustrated by the accompanying photographs which show the fruit of the plant as well as the primocanes; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are 2 years old.

FIG. 1 shows a section of a young cane with prickles.

FIG. 2 shows both the upper surface and the lower surface of the plant leaves.

FIG. 3 shows (from left to right, from top to bottom) a flower bud, an immature fruit, an immature fruit, a mature fruit, the fruit plug, and immature fruit.

DESCRIPTION OF THE NEW VARIETY

The following description of ‘DrisRaspTwo’ is based on observations taken from the 2005 to 2009 growing seasons in Santa Cruz, Calif. This description is in accordance with UPOV terminology. Color designations, color descriptions, and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. ‘DrisRaspTwo’ has not been observed under all possible environmental conditions. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001 edition).
